Specific implementation mode：
Referring to figs. 1 to Fig. 4, the pulley blocks with stop protection, including component plate 1, mobile side board 2 and pulley 3, component plate 1
Upper and lower end is both provided with cord hole 11, and upper end is arranged a cord hole 11, can be suspended on fixture by the cord hole 11；Especially
Lower end is uniformly distributed there are three cord hole 11, has great convenience on installing multiple determining points, with component panel assembly
With function.
Pulley 3 is located in by an axis 4 between component plate 1 and mobile side board 2, component plate 1 above axis 4,
It is additionally provided with an axial elasticity pin 5 for being parallel to axis, the top of mobile side board 2 is locked by the resilient key 5, it is whole to form one
Body, and mobile side board 2 can be opened at any time, it is convenient for wire rope handling or emergency processing.Resilient key 5 includes a key seat 51, cylindrical spring
52 and shank 53, there is key seat 51 cylinder chamber 511, cylinder chamber radially to offer elongated slot 512；51 one end of key seat is fixed on component plate
1 surface is sequentially placed into cylindrical elastomeric 52 and shank 53 in cylinder chamber 511；Shank 53 is radial to be provided with spacer pin 531, the limit
531 projection of pin forms the positioning of shank 53 in the elongated slot 512 of cylinder chamber, and the retraction of shank 53 can be released on mobile side board 2
The constraint in portion.
In this example, 1 both sides of component plate are disposed with pulley 3 and mobile side board 2 respectively, and are formed by an axis 4
Positioning；1 both sides of component plate are provided with corresponding axial elasticity pin 5, and mobile side board 2 top in both sides offers pin hole 21, by
Resilient key 5 springs into the location structure that pin hole 21 forms mobile side board 2.
Stop cam 6 is arranged on the component plate 1 above pulley 3, is located on component plate 1 by guide shaft 61, the guide shaft
A torsional spring 62 is arranged on 61, stop cam 6 remains the trend for pressing to 3 working face of pulley under the effect of torsional spring 62.More
It says to body, stop cam 6 is in crescent shape, and one end is located on component plate 1 by guide shaft 61, has a button on the intrados at the end
The extrados of tongue 63, the other end is convexly equipped with pawl 64, increases the friction with 9 surface of rope, such as Fig. 2.
Locked in component plate 1 by bolt 9 in 5 periphery setting of resilient key, one Insurance Block 7 and insurance wraping plate 8, the Insurance Block 7
On, which is in circular ring structure, is provided with the wraping plate chamber 72 of the stroke notch 71 and accommodating insurance wraping plate 8 of stop cam 6,
72 bottom of wraping plate chamber also has cylindrical portion, to one end of containing and limit resetting spring；Insurance Block 7 is not only insurance wraping plate
8 provide installation space, while being also that mobile side board 2 provides spacing benchmark with component plate 1.
Insurance wraping plate 8 is located in by axis on Insurance Block 7, and 8 one end of insurance wraping plate is vertically provided with clasp 81, other end bottom
It is provided with resetting spring 82 namely 82 one end of resetting spring between portion and wraping plate chamber 72 and contradicts cylindricality in 72 bottom of wraping plate chamber
Portion, the other end are contradicted in the bottom of insurance wraping plate 8, and insurance wraping plate 8 forms anti-skidding ripple 83 in the end another side, provides hand pressure
Operation needs.Wraping plate 8 is insured under the effect of resetting spring 82, and clasp 81 is contradicted always in the back side of stop cam button tongue 63, system
Stopping after cam 6 is flipped up design angle, clasp 81 slides into 63 lower section of button tongue, forms the locking structure to stop cam 6, this
The locking that the stop cam 6 referred to is opened is locked, so as to operations such as wire rope handlings；Once at the anti-skidding ripple 83 for pushing insurance wraping plate 8, i.e.,
The constraint to stop cam 6 can be shed, stop cam 6 acts on the working face for pressing to pulley 3 in torsional spring 62, in due course to rope stop
Protection, and the operation of rope closing is not influenced, greatly take precautions against the downslide of lifting weight.
This pulley blocks can form the above labor-saving structure of two-stage with another pulley or same pulley blocks, and 9 one end system of rope has
Weight, the other end sequentially pass through each pulley, and open end is rope closing end, provides manpower or power rope closing, especially in manpower rope closing,
It is necessary that setting stop, which is protected, and stop cam 6 has an one-way, and counterweight object space is to anti-skidding effect, and rope closing direction
Non-resistance.
Pulley blocks operation principle and feature with stop protection：
One, this pulley blocks are protected with unidirectional stop, and stop cam 6 remains under the effect of torsional spring 62 by rope
The trend of pulley 3 is pressed to, once decontroling both hands, pulley blocks will produce stop, and do not influence forward direction and make power lifting heavy；
Secondly, when pulley blocks be positioned at determine point after, even at the pulley blocks of stress, mobile side board 2 also may be used
To open, facilitates installation or remove rope；On the other hand, in rope work stress, adjustment rope work state can also be relaxed；
In addition, mobile side board has self-locking function, not only globality is strong, is also convenient in opening operation；
Thirdly, stop cam 6 open after can be positioned by insurance wraping plate 8, the operations such as convenient retracted rope；
Four, component plate 1 is forged by high-strength aluminum alloy, excellent load bearing capacity, and intensity is high.(1) component
Plate has great convenience on installing multiple determining points, according to the usage requirement, in rescue and lifting heavy, accomplishes arbitrary peace
Row determines the working range of point, and makes work station that a direction be determined that the strength of point uniformly distributes to another more in order
Multiple determining points in direction, aerial suitable for tethered system cross.Balance weight can be helped with the vertical transport system on rope
Object, and can prevent rope from being distorted when bearing a heavy burden；(2) determine that the resultant force connection button hole of point buckle connects button hole with component, Ke Yirong
Perhaps the locking a door for safety door hook of any line footpath passes through.
It is that the preferred example of the present invention and functional characteristics describe above, it is every according to structure of the invention essence, only to being related to
The update or variation upgrading of the contents such as material, appearance and modeling, size shape, belong to patent category of the present invention.
